Half-skyrmion picture for high-temperature superconductivity and its simulation in cold atoms
T Morinari
Show affiliationsA half-skyrmion spin texture scenario is proposed for high-temperature superconductivity. It is argued that the half-skyrmion spin texture is created by doped holes through the Zhang–Rice singlet formation. Performing a duality mapping, the effective action of the half-skyrmions is obtained. Phase fluctuations of the spins are described by a gauge field. The magnetic Lorentz force like effect is induced between a doped hole and a half-skyrmion or an anti-half-skyrmion created by another hole. It is shown that such an interaction leads to 
-wave superconductivity. Simulating the picture in a cold atom system is proposed.
